【発明の詳細な説明】
本発明は継ぎ手用フランジ等の鍔状部を有する熱可塑性
樹脂パイプの製造法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a thermoplastic resin pipe having a flange-like portion such as a flange for a joint.
従来、熱可塑性樹脂パイプに継ぎ手用フランジ等の鍔状
部を設ける場合、射出酸形成は熱可塑性樹脂ブロックの
切削加工によって得た鍔状部を熱可塑性樹脂パイプにパ
ット溶接又は接着剤等で接着する方法があった。Conventionally, when providing a flange-like part such as a joint flange on a thermoplastic resin pipe, injection acid formation is performed by pad-welding the flange-like part obtained by cutting a thermoplastic resin block or bonding it to the thermoplastic resin pipe with an adhesive. There was a way to do it.
上記の方法によれば、熱可塑性樹脂パイプと鍔状部の接
着強度が充分ではなく、更に射出成形においては金型の
償却費を要し、切削加工においては切削屑が無駄になり
加工工数も要するために製造コストが高くなる等の欠点
があった。According to the above method, the adhesive strength between the thermoplastic resin pipe and the flange part is not sufficient, and in addition, injection molding requires depreciation of the mold, cutting waste is wasted, and machining man-hours are also reduced. This has disadvantages such as increased manufacturing cost.
本発明は上述の如き欠点を除去するもので、熱可塑性樹

体に成形したパイプを製造するものである。The present invention eliminates the above-mentioned drawbacks, and uses a thermoplastic resin pipe as a core material, and a belt-shaped thermoplastic resin sheet extruded from an extruder while heating and melting the surface of the core material is still molten. While the pipes are softened, they are stacked, rolled up, and fused to produce a pipe in which a core material is integrally formed with a flange-like part used as a flange for a joint, etc.

を有するパイプを製造するものである。Next, an embodiment of the present invention will be described. The core material 1 of a thermoplastic resin pipe is rotated in the circumferential direction while the end surface of the core material 1 is uniformly heated and melted, and a band-shaped material is extruded from an extruder. Thermoplastic resin sheets 2 are heated at the flange of the core material 1, and the melted portion is stacked and rolled up while controlling the width, and while the thermoplastic resin has a temperature above the melting point, the core material 1 is heated and rolled up using a pressure roll. The flange-shaped part 3 is integrated with the flange-shaped part 3 by cooling and solidifying it under pressure.
The purpose is to manufacture pipes with
上述の如く本発明においては、鍔状部と芯材となる熱可
塑性樹脂パイプを一体成形しているため熱的歪みが少な
く、鍔状部を継手用フランジとして使用する場合にも強
い強度を発揮できる。As mentioned above, in the present invention, the flanged part and the thermoplastic resin pipe serving as the core material are integrally molded, so there is little thermal distortion, and the flanged part exhibits high strength even when used as a flange for a joint. can.
また、金型の償却費切削加工の工程等がないため製造コ
ストも下げることができる。In addition, manufacturing costs can be reduced because there is no cutting process or the like to depreciate the mold.
更に芯材の全長にわたって適当間隔に鍔状部を設ければ
補強されたパイプを製造できるし、また芯材の両端に鍔
状部を設けて電線ケーブルの巻芯等も製造でき、工業的
価値極めて大なるものである。Furthermore, by providing flanges at appropriate intervals along the entire length of the core material, reinforced pipes can be manufactured, and by providing flanges at both ends of the core material, winding cores for electric wire cables, etc. can be manufactured, which has industrial value. It is extremely large.
